"registering" a generic method for a class
Sorry in advance if this is too simple a question, but I'm stuck with some odd behavior and I can't find the text to rid myself of this (admittedly somewhat trivial) problem. Note that I've done generic programming with S3 "objects" in the past, but I've never really dabbled in creating S4 objects until now. So, I've created a new S4 class, call it

Unexpected failure when calling new() with unnamed arg and
Hi, The man page for new() suggests that if 'a' is an object with slots "slot1" and "slot2" and C is a class that extends the class of 'a', then the 2 following calls should be equivalent: new("C", a, ...) new("C", slot1=a at slot1, slot2=a at slot2, ...) This is generally the case but I just ran into a situation where it's not.

Seeking help to define method for show() for an S4 object
Dear all, I have created a new S4 class with name "MyClass". Please see below for it's definition. Now I want to create a method for the show() function for this class. In defining this method, what I want is, once user would like see an object of this class some values will be displayed. Then R will ask for **press Enter**. Once user presses enter then, remaining values will be

OOP with Encapsulated Class Definitions
Hi all, I'm seeking feedback (good, bad or indifferent) in regards to developing (further) a new class system for R, that uses encapsulated class definitions (i.e. the method definitions are literally inside the body of the class definition). A working (however very rough and poorly tested) system is available in my R package "oosp" with documentation in the vignette

S4 'properties' - creating 'slot' functions?
Dear R users! Several languages like C# or VB allow one to create properties; typically these are under 'get', 'set' tags. My question is this really, what are similar or comparable strategies in R, and what might be preferred? I have a couple of situations where I want a certain computation to belong to a class, but I do not really want to seperate it out to a stand-alone

RoR: recognizing a defined class
Hi all, I am very new to Ruby and I have a silly question: how do I get RoR to "recognize" that I just defined a class? To be more explicit, I have a controller and view, and then I want to create a class and get the controller to "see" it. So, I created a file called "myobject.rb" in the models/ directory and inside it defined "class myobject [...] end".

Subsetting Method [ Revisited
Hello Everyone: As usual, thanks in advance for any help. I was hoping to get some more advice on this question: I'm trying to write a subsetting routine for an S3 object I've created -- lets call it myObject. myObject has a few attributes basically of type string and numerics. Its atomic value is just a vector of ints. I want to write my own subsetting routine to subset myObject in

For instance, SpatialPolygonsDataFrame objects have obviously a plot method. However it cannot be found in the list provided by methods(plot) . Furthermore ?plot.SpatialPolygonsDataFrame, nor ?plot.SpatialPolygons, etc.. provide a help, though the lattice
